neutron-keepalived-state-change_as_dash_script.patch Replace keepalived-state-change by a dash script This patch replaces the Python script to monitor the "keepalived"
status of a router instance with a bash script.
.
The Python implementation of the keepalived state change monitor
consumed approximately 100MB of RAM per router monitor process. This
becomes problematic when running many HA routers on a single node.
.
This patch replaces the Python daemon with a lightweight POSIX shell
script (dash-compatible) that consumes only ~6MB of RAM per router
monitor (this includes all children process, including "ip"),
representing a 17x improvement in memory efficiency.
.
Key changes:
- New shell script: bin/neutron-keepalived-state-change
* Uses /bin/sh (dash on Debian/Ubuntu) for minimal memory footprint
* No bashisms to ensure portability across distributions
* Proper signal handling and cleanup of child processes
- Added new logging configuration options in conf/agent/l3/config.py
to allow central logging instead of one log per router spread across
many ha_confs folder:
* per_router_log_files: Include router ID in log filename
* router_log_files_in_ha_confs: Store logs in router's ha_confs dir
* No change of previous behavior
.
- Memory usage comparison:
* Old Python implementation: ~100 MB per router monitor
* New shell implementation: ~6 MB per router monitor
* Savings: ~94 MB per router (94% reduction)
* For a node with 250 HA routers: ~25 GB of RAM saved
.
This also to improves the stability. This shell script do not uses
threads to monitor the IP addresses, as in the Python script. It
uses an "ip -o monitor" context that exits every seconds and acts
on its output.
